Fig. 11 in Sieve-type normal pore canals in Jurassic ostracods: A review with description of a new genus

Fig. 11. Distribution of macro sieve-type normal pore canals (StPC-M), micro sieve-type normal pore canals (StPC-m), and simple normal pore canals NPC) on the inner side of cytherid ostracods Minyocythere gen. nov. and Dolocythere Mertens, 1956. A. Minyocythere macroporosa sp. nov., holotype, SMF Xe 23721 from Borehole Hambühren WA2, 166 m, NW Germany, Witchellia laeviuscula Zone (Braun Jura γ), Lower Bajocian; male left valve. B. Dolocythere rara Mertens, 1956, SMF Xe 23756 from Borehole Rodewald WA6, 206 m, NW Germany, Lower Albian; male left valve (B1), detail (B2). C. Minyocythere sp. cf. M. macroporosa sp. nov., SMF Xe 23724 from Borehole Rodewald WA12, 386 m, NW Germany, Upper Aalenian (Braun Jura β upper); male right valve. D. Dolocythere amphistiela sp. nov., paratype, SMF Xe 23765 from Borehole Rodewald WA4, 187 m, NW Germany, Leymeriella tradefurcata Zone, Lower Albian; male left valve. In A and C, black dots refer to StPC-M, white arrows point to StPC-m; in B1, B2, D white arrows point to NPC; black arrows in B1, B2 indicate the peculiar pores of D. rara (which do not exist in D. amphistiela). Scale bars 100 μm.
